---------------------------------------------------------------------***--------------------------------------------------------------------Abstract - Flywheels serve as kinetic energy storage and retrieval devices with the ability to deliver high output power at high rotational speeds as being one of the emerging storage energy technologies is available today in various stages of development feild, especially in advanced technological areas. Many causes are there of flywheel failure among them and one of is the non-linear behavior of the flywheel. Hence this work evaluation is done of non-linear stresses in the flywheel for different material . The solid work software used fordesign of flywheel. The ANSYS software is used for analysis and apply forces for validation of flywheel is. The FEA of flywheel is considering centrifugal forces on its comparative non-linear analysis von-mises stress is done, shear stress and deformation of the flywheel made of Cast iron and aluminum alloy. The paper gives too topology optimization approach in the mass of flywheel reducing.

The word ‘flywheel’ appeared first during the start of industrial revolution. There were two important developments during this period, one is the use of flywheels in steam engine and other is widespread use of iron. Iron material has high integrity that flywheels made up of wood, stone or clay. Flywheel is a device (mechanical) which is used as a storage device for rotational energy due to its significantly high moment of inertia. Flywheels are required where there is a fluctuation in input power and output load is constant or there where is a fluctuation in output load and the input power remains constant Flywheel is like as a reservoir to store energy when supply is more than requirement and to release the energy when requirement is more than supply. Flywheel provides an effective way to smooth out the fluctuation of speed.

1.2 Problem Statement The flywheel is dynamic part hence the non-linear static analysis does not gives the exact value of stresses developed in flywheel. It is difficult to find out such type of stresses with the help of numerical analysis to overcome these problems. Modern technologies are used such as FEA software. The paper deals with the study of stresses induced in a flywheel made of different material by using non-linear analysis. © 2017, IRJET

To study the stress induced in Subaru EJ25D gasoline engine flywheel.. FEM Modeling of Flywheel Perform Non-Linear Analysis using ANSYS. Consideration of flywheel model for shape optimization. Experimental Validation.
4.
To use FEA/FEM as method and software to find the stresses in the flywheel. Optimize the flywheel for reduction in cost & high fuel efficiency. Perform non linear analysis to find the best suitable material for flywheel manufacturing. And most important is dynamometer test perform on flywheel, etc.
2. COMPUTER ADDED MODELLING & FEA 2.1 Introduction to Solid works Solid works is based on a single database, parametric, and modular process-oriented PLM system. Today all over the world as businesses, small, SMEs and large industrial companies from all sectors to all types of design processes and product development, production machinery, moulds, household appliances, automotive, agricultural machinery ,shipbuilding, electrical / electronics, medical products, telecommunications, household appliances, metal products, heating and cooling and the manufacturing sectors such as defence and aerospace design and product development processes of all types of co lateral industries, universities , institutes of technical education institutions and R&D is the software used. This is the result of the different sectors to respond to the modular structure.
